Transaction prices continue to rise at a slower pace, with October’s estimated average transaction price expected to rise by $101 from a year ago to $35,263, Kelley Blue Book (KBB) reported on Tuesday. Compared to September, the firm expects the average to increase by $128, or 0.4%.

April retail sales are expected to reach 1.17 million thanks to record incentive spending. However, average days to turn continues to rise, with nearly 30% of vehicles sold so far in 2017 having sat on dealer lots more than 90 days.

Southeast-region auctions are seeing a seasonal increase in values driven by tax-return-driven buying at dealer lots, but say the spring bump isn't as pronounced in 2017 in part due to the delay by the IRS to issue returns in late February.
